Abstract

A computer-implemented method for analyzing multivariate data comprising a plurality of samples of each of a plurality of measurement variables is disclosed. The method comprises, for a first subset φΑ (X) of the multivariate data X, determining (110) a first projection score related to the first subset. Furthermore, the method comprises, for a second subset φB (X) of the multivariate data X, determining (120) a second projection score related to the second subset. Moreover, the method comprises, comparing (130) the first and the second projection score for determining which one of the first and the second subset provides the most informative representation of the multivariate data, which is defined as the one of said subsets having the highest related projection score. A definition of the projection score is also provided.
